Virtual touch screen technology can also be applied to turn non-touch displays into interactive, touch-capable surfaces using a Kinect sensor in combination with a projector. [14] This type of application allows virtual touch technology to enhance personal display usage as well as better communication and presentation of data to be used in ...
A touchscreen (or touch screen) is a type of display that can detect touch input from a user. It consists of both an input device (a touch panel) and an output device (a visual display). The touch panel is typically layered on the top of the electronic visual display of a device.
The basic idea is to replace the touch module glass with a thin layer of insulating material. In general, there are two ways to achieve this. One approach to OGS is called "sensor-on-lens” (also known as “touch-on-lens” or “sensor-on-glass”), with the "lens" in this case referring to the cover glass layer.
An LCD screen used as a notification panel for travellers. Each pixel of an LCD typically consists of a layer of molecules aligned between two transparent electrodes called alignment layers, [citation needed] often made of indium tin oxide (ITO), and two polarizing filters (parallel and perpendicular polarizers), the axes of transmission of which are (in most of the cases) perpendicular to ...
An interactive whiteboard (IWB) device can either be a standalone computer or a large, functioning touchpad for computers to use. Interactive whiteboards are widely used in classrooms, boardrooms, and training environments, providing an innovative way to share information, facilitate discussions, and enhance the overall learning or business communication experience.

A touch user interface (TUI) is a computer-pointing technology based upon the sense of touch ().Whereas a graphical user interface (GUI) relies upon the sense of sight, a TUI enables not only the sense of touch to innervate and activate computer-based functions, it also allows the user, particularly those with visual impairments, an added level of interaction based upon tactile or Braille input.
Video overlay is any technique used to display a video window on a computer display while bypassing the chain of CPU to graphics card to computer monitor. This is done in order to speed up the video display, and it is commonly used, for example, by TV tuner cards and early 3D graphics accelerator cards.
